They bored under a driveway at a distance of 50ft and it took about 30 minutes. It comes with a 2" bit but also you can purchase a 3" and a 5" bit. Check out their website at www.Borzit.com.

I have a kit of drive points and drive caps that I can screw on RMC and sledgehammer it under sidewalks and such. Works pretty good. Never did under a driveway. I use a sub for that sort of work.

this topic was discussed before.

several home grown applications exist.

my own I got from a plumber and I can vary it. I have a 2" heavy spade bit on a steel rod that I use for under sidewalks (holehawg on low works just fine) and I start a long hole with that bit, then use a water auger for the rest. Each use is specific to site and pipe so it would be impossible to try and describe all the variations. threaded rigid can be part of the auger, just add coupling and nipple. blow dry with compressor if picky.
